What are alternatives that involve not accepting refugees? Shoving thousands of people into refugee camps in Turkey has some pretty big problems associated with it, and it's not like
refugee camps can become militarized or anything
Being sent to a refugee camp in Turkey may not be pleasant (nobody said refugees are entitled to pleasantness), but it's not akin to genocide or torpedoing boats. This sort of hysterical and dishonest rhetoric serves no purpose other than making the people using it look like fools out of touch with reality. It's certainly not being bought by the people, judging by recent electoral results and the radical backtracks of several European governments on their refugee stance.
Anyway, the point that a lot of people made was never that all refugees are illegitimate or whatever. It was always that Merkel made the crisis much worse by essentially accepting everybody in, and openly stating she wouldn't enforce the EU's asylum rules. This caused a huge influx of people who were not refugees at all - Moroccans, Egyptians, Pakistanis, and hordes of people from the West Balkans.
What people have also been saying is that Europe can't take millions of refugees in one year, specially because they tend to concentrate in just a few countries. Realism must speak louder than all other considerations; see what happened to Sweden and how they completely backtracked from their historical refugee stance.
The hordes of young males who made it to Germany or Sweden are not particularly vulnerable and are certainly not escaping from a war zone, as they crossed several safe countries. So there's no reason why Germany or Sweden should accept millions of them, and in fact it's simply not possible to do so.
Now Europe is turning to the far-right.
(BTW there's still a chance that the far-right won't win in Austria, it's too close to call. But the message was given loud and clear anyway.)
Edit: Also, do you know that Brazil offered to take on 100,000 Syrians? But less than 15,000 took on the offer, because salaries are low and welfare benefits are scarce in Brazil. Again, there is nothing wrong with being an economic migrant and trying to make it to a country with brighter prospects. But lets not confuse that with refugees in need of protection from immediate danger. When the shopping for the most attractive location starts, the refugee status ends.
